1INTRODUCTION
The GI51 is a multi purpose interface unit designed for
converting various input signals to Robnet, sin/cos, stepper
signal, NMEA 0183, and Clock Data output signals. Refer
TECHNICAL SPECIFICATIONS, page 20.
The GI51 may be used both in a Robnet system and as a stand-
alone unit.
Note! If GI51 is used together with the AP20 or AP35/16, it must be
configured as stand alone.
The unit has a pendulum ferry feature that will change the
heading output by 180° on command when the unit is connected
to Robnet. If not connected to Robnet, an optional GI51 function
key is required to activate the pendulum ferry function. Refer
PENDULUM FUNCTION KEY (Option), page 16.
2INSTALLATION
2.1 Mechanical installation
The GI51 should be mounted with regard to the environmental
protection and temperature range of the unit, and should not be
installed in area exposed for heavy vibrations.
Make allowances for working area around the unit when routing
or removing the cables.
Fasten the GI51 to the bulkhead. Refer mechanical drawing,
page 20.
2.2 Cabling
All cable conductors are terminated in screw terminals on the
GI51 pcb.
Connect equipment according to the block diagram on page 6,
and to Terminal description, page 13 onwards.
To make a good ground connection, strip about 1 cm (0.4”) off
the cable’s insulation and pull the screen backwards to cover the
insulation. Position the straps as shown in the figure. Tighten
well to make sure the screen makes good contact.
This will also avoid vibration causing the cables to loose
connection.
Note! Be careful not to drop screen cuts over the components!

2.3 Dip switch settings
The following dip-switches have to be set correctly:
-SW1-1 and SW1-2 determine the gearing ratio for synchro
input. For 1:1 synchro or if synchro is not used, both are
set to OFF
-SW1-3 determines the format of the clk/data heading
signal to the radar. If the unit is powered by the Robnet,
the format is set from the autopilot control unit. Hence the
switch is not used and the settings for the switch is
irrelevant.
-SW1-4 can be used for test and trouble shooting (ref. page
17). When the switch is set to ON, the heading at all
outputs will jump in circles in a sequence of 45° each 10
sec.
-SW2-1 set to OFF gives NMEA and Robnet speed output
from the pulse log input. If set to ON, speed will be taken
from the longitudinal water speed field of VBW
(1.priority) or VHW (2.priority) of the NMEA input.
-SW2-2 is used to determine the internal gain for high
voltage 50-100V ref. (L/L or low voltage, 26V ref., 11.8V
L/L synchros. OFF sets the gain for high voltage level
(others), ON sets the gain for low voltage, 26V/11.8 V
L/L.
All switches are factory set to OFF.
For location of the dip-switches, refer to Component location,
page 12.

2.4 Interface setup procedure
When a compass is connected to the GI51 via Robnet, it is
required to configure the compass in the autopilot Interface
Setup Menu.
Note! For AP50 the gyro type has to be selected under the “GI-menu”
shown in the Interface menu.
The procedure to access the Interface Setup Menu is detailed in
the respective autopilot manual.
If more than one compass is connected to a GI51, operating as
“stand alone”, the input compass will be selected at power on in
the following order: Synchro (1.priority) →Step →RGC →
NMEA.
2.5 Offset adjustment
Without Robnet connection to GI51, heading offset adjustment
is required after power on. This can be done either by a
proprietary NMEA data (ref. page 22) or by an external switch
connected between the SEL 3 and +12V.

The switch must be a potentional free pulse type. When pressing
and holding the switch, the heading will increase or decrease,
depending of last direction control.
The heading will increase in a slow rate for the first 2 degrees,
but change to high rate for as long as the switch is depressed. By
making a quick double press and keep the last press, the
direction is reversed and started with low rate. Single presses on
the switch changes the heading by one tenth of a degree.
The switch should be mounted in a location for convenient
operation.
Note! Make sure that the switch is mounted on a protected area to
avoid unintended operation that will give large heading changes!
